Sentinel incidence angle and pass

Hi @SudiParwata, the corner reflector will reflect in the same polarisation as it receives. So for S1 VH mode, the SAR transmits in V polarisation and receive in H polarisation. In this case the CR reflected polarisation is V but the SAR itself will only detect RF signals in H polarisation. Thus no signal will be received from the CR.

Dear @peter.meadows
Oh yeah, I forgot the basic things about polarization concept.
Thank you very much for your explanation.
Thanks also your detail and very clear about:

  1. How to use above-heaven
  2. Base angle
  3. Azimuth angle

Regards,

Hi Peter. I have several doubts and I hope you can help me.

  1. I have entered my coordinates in HA, I select all the passes and it shows me data for continuous dates and not every 12 days as it is supposed to be shown already indicating the coordinates of interest.

  2. If in the metadata of my image it indicates that the image was taken at 10:59 AM and in HA there are only data with time of 5:04 AM, 7:24 AM and 18:01 AM. Therefore, from what time should I take the data for calibration? From the time closest to the time the image was taken?
